    • forceLoad

      public static void forceLoad() throws IOException
      Force load the library.
      Throws:
      IOException - thrown if the native library cannot be found

    • sendCANMessage

      public static boolean sendCANMessage(CANBus bus, int messageID, byte[] data)
      Sends a CAN message. (At the moment, this more or less calls HAL_CAN_SendMessage under the hood, and does not support sending to non-Rio buses.)
      Parameters:
      bus - the bus to send on
      messageID - 29-bit full CAN message id
      data - payload of up to 8 bytes.
      Returns:
      success

    • sendCANMessage

      public static boolean sendCANMessage(CANBus bus, int messageID, long data, int length)
      Sends a CAN message using a long as the data medium. (At the moment, this more or less calls HAL_CAN_SendMessage under the hood, and does not support sending to non-Rio buses.)
      Parameters:
      bus - the bus to send on
      messageID - 29-bit full CAN message id
      data - payload of up to 8 bytes, formatted as a little-endian long.
      length - data payload length.
      Returns:
      success
